Verdict
The clearest difference is rating: Peptide at 5.0 against PeptideJournal's 4.3. Peptide also leads on price ($4.99 vs $5.99). PeptideJournal's advantage is ratings volume (20 vs 1) and chart position (#198 vs unranked). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
